[DOCS] editable__columnname is not documented

[AlexandreSajus]

Issue Description

The proper syntax to make the "Demand" column of a table editable in tgb is:

tgb.table("{demand_table}", on_edit=edit_demand, editable__Demand=True)

But this syntax is not documented in the docs: https://docs.taipy.io/en/develop/manuals/userman/gui/viselements/generic/table/ https://docs.taipy.io/en/develop/tutorials/visuals/2_using_tables/
